usually carried. through a dust chamber in which the heavier dust settles out; the bal- V ance of the suspended material and the fume being then forced through a bag house to filter out the finely divided and "see ended material before the fume is finally disc iarged into thestack.

This invention provides certain improvemerits in such baghouses, and in apparatus for shaking down bags used in this and sinnlar locations.

The bag house is provided with a floor which divides it into one or more bag rooms sage.

above, anddust cellars below. The bags are usually of muslin or woolen and arranged in the bag'room's with'the'ir upper ends closed and their lower ends communicating through the. floor. with the dust cellar. The dustladen fame is conducted into the cellar, and thence up through the open lower ends of the bags, and passes through the mesh of the bags, t 'e' dust being filtered out in such as- From the spacesurrounding the ags in the bag room the filtered fume is conducted by an outlet fine to the stack. It is nec:

essar to shake the bags from time to time, usua y once a day, so t to the inside of these will dropto the floor of the dust cellars, the bags being shaken by a man who enters the bag room for the purose. The man who shakes the-bags must well protected from the fumes. Accord ing to the general'practice at present, he

wears a rubber suit, and over his head a helmetcarrying a supply of compressed air for himto breathe. I

According to this invention a mechanical arrangement is provided whereby the bags may be shaken more efficiently than by hand and from the outside of the room, so that it is not necessary to open to the atmosphere.

the room in which the bagsare being shaken. The apparatus also permits of theshaking of a-large number of bags at once, thereby saving much time. A very eflieient movement is given to the-bags by shaking them at the top with a wavy motion which travels from at the dust adhering top to bottom andfrees the dust much better than the motion imparted by the hand shaking by a man on the floor. The bags being rigidly tied at the bottom, it is diflicult to shake them well from a point near the bot tom.

The accompanying drawings illustrate an embodiment of the invention.

' Figure 1 is a plan and horizontal section, and Fig. 2 an elevation of a complete bag house With fines and stack connected therebag house and adjacent fines; Figs. 4,5 and 6 .are respectively a plan, and a transverse and alongitudinal section of a part of the shaking apparatus; Figs. 7 and 8 are diagrammatic slde and end views of adiiferent style of shaker embodying the invention; Figs. 9,

. 10 and 11 are respectively a diagrammatic plan, side elevation and end elevation of another arrangement of the shaking app-aratus; Fig 12 is an enlarged sectional view of one of the bags and its top andbottom per connection at right angles to Fig. 12; Figs. 13 and 14 are enlarged details of the upper ends of the bags slightly modified.

Referring now to the embodiment oi/the invention illustrated, the fame enters by way of the line A and passes by way of a number of valved branches B to the different sections of the dust cellar C, and thence up through site the inlet fine, and a track 0 may be arran ed to run along the front of the house cellars for conveniently handling the dust.

outer walls Q and partition Walls R, and a roof S preferably of asbestos composition. 'lhe'house is divided in thev present case for example into five rooms, andthe dust cellar to; Fig. 3 is a'tran'sverse section through the I the steel thin'ible floor D into the bottoms oithe bags E, after passing through the with branches P running into the several dust The bag rooms are surrounded by masonry connections, Fig. l2 being a view of the upmo tions of the dust cellar and at the side oppo lie house without interfering with the operation of the other parts. Each room preferably carries a large number of bags, and these bags are quite high.. For example the rooms shown may be providedeach with about 400 bags 30 feet high. It will be appreciated that the efficient shaking of such bags by aman standing on the floor D is difficult, and

that the arranging of the'shaking apparatusthe chords U and upon the walls-of the-build-' 4 which bags are fastened. The shafts W are so that a single lever operates a number of bags, very much facilitates the operation.

The bags may be mounted in various ways. In the arrangement shown their up er ends are supported by the lower chords Bot. the roof trusses. A number of transverse beams, such as the channels V, are supported upon ing, as shown best in Figs. 4, 5 and 6, and upon' these transverse beams are sup orted in suitable bearings a number of 'sha ts provided with depending arms. X, to the lower ends'of connecte in roups by means of upwardly ex+ tending arms to the upper ends of which is connected for each group a horizontal bar Z. M

By reason of this connection the oscillation of one of the shafts results in a corresponding oscillation of all the shafts in the same group. One shaft in each group is accessible from the outside, as b running the end of the shaft throughthe wa Q of the building, and roviding it on its outer end With'ahand e a.

I Each bag as its supporting arm X swings from side to -ment shown in Figs. 7 and 8.

A similar e ect is obtainable from the arrange- Here the rotary shaft W is su ported upon the wall or upon transverse or ongitudinal beams, and is provided with an offset portion h to which the several bags E of a group are connected,-

so that as the shaft W is swung a vertical and also a horizontal movement is obtained similar to that roduced by the arms X of the previously 7 es'cribed construction.

- Inthe'arrangement shown in Figs. 9, 10 and 11-, a shaft W is oscillated by the outside handle a, and is rovided within the house with an arm j w 'ch operates a horizontal bar 7c ivoted to the ends of arms Z upon vertical s afts m lying at the-side of or eccentrlc with the vertical axes of the bags, and provided with arms a which areconnecte'dto the ba s.

The attaching of the to' of the bag to the end of an arm on an osc' ating shaft in the -manner shownyis designed to effect chiefly a horizontal wav motion which will travel from the top to the bottom of the bag and shake it out ve effectively and without the strain that woiild accompany a sim le vertical reciprocation of the. tofp of t e bag.
